Dip one of the cotton swabs in water and dab the water on the petal on the wax paper labeled “Water.”

Using the needle, pierce one of the vitamin E capsules and squeeze a drop of vitamin E oil onto the petal on the wax paper labeled “Vitamin E.” Use a cotton swap to gently spread the oil over the petal.

Leave the petal on the wax paper labeled “Air” untouched.

Repeat Steps 4 – 6 daily for 5 days. Be sure to use new cotton swabs each day.
